Q

Ovarian Neoplasms

A
  • 80% benign
  • Mostly young women 20-45 years
  • Borderline tumours at slightly older age
  • Malignant tumours – older women 45-65 years
19
Q

Investigations for Ovarian Cancer (2)

A
  • CA125 Blood Test
  • Transvaginal Ultrasound
20
Q

Types of Epithelial Ovarian Tumours (5)

A
  • Serous
  • Mucinous
  • Endometrioid
  • Clear Cell
  • Brenner (transitional cell)
21
Q

What are Sex Cord Stromal Tumours?

A
  • These are neoplasms which frequently produce
    steroid hormones
  • May be benign or malignant
22
Q

Types of Sex Cord Stromal Tumours (3)

A
  • Granulosa Cell Tumour
  • Thecoma
  • Leydig Cell Tumour
23
Q

Embryonic Ovarian Germ Cell Neoplasms: What is an Immature Teratoma?

A

A type of malignant germ cell tumour that is often made up of several different types of tissue, such as hair, muscle, and bone

24
Q

Embryonic Ovarian Germ Cell Neoplasms: What is a Dysgerminoma?

A
  • A type of cancer that begins in germ cells in females
  • Malignant
  • Oocyte pure malignancy
  • Very radiosensitive, so good prognosis
25
Embryonic Ovarian Germ Cell Neoplasms: What is a Monodermal Tumour?
Benign
26
Extra-Embryonic Ovarian Germ Cell Neoplasms
* All are Malignant * Yolk Sac Tumour * Choriocarcinoma * Endodermal Sinus Tumour
27
What are Krukenberg Tumours?
It is a metastatic disease to the ovaries composed of mucin-rich signet-ring cells, comes from gastric cancer cells
28
Extra-Mammary Paget's Disease (EMPD)
* It is a rare, slow-growing disease that is a pre-invasive form of skin cancer * Presents as pruritic red area on labia majora or around nipple * Mucin containing adenocarcinoma cells in the epidermis
29
Gestational Trophoblastic Disease: Placental Tumours (3)
* Hydatidiform Mole: Partial or Complete Mole * Invasive Mole * Choriocarcinoma
30
What is a Hydatidiform Mole?
* Is a rare mass or growth that forms inside the womb (uterus) at the beginning of a pregnancy * Grape like villi, holes * Monitored by HCG levels (serum and urine) * If level rises, patient will receive chemotherapy * Neoplastic potential of complete mole greater than partial mole * Followed up and patients advised not to get pregnant
31
What is a Choriocarcinoma?
* Rare malignant tumour associated with high mortality * Usually follows hydatidiform mole, can follow miscarriage or very rarely normal pregnancy * Malignant tumour of trophoblast: syncytio- and cytotrophoblast in layers
32
What is CIN?
Cervical Intraepithelial Neoplasia 3 Degrees: I, II, III
33
What part of the cervical epithelium more commonly becomes cancerous?
Ectocervical Epithelium
34
What morphological change does HPV cause in the cervix?
Koilocytosis
35
Normal vs Abnormal Ectocervical Epithelium
* Large cells, small nucleus * Larger cells, darker stain, larger nucleus
36
What does Carcinoma in situ mean?
Basement membrane is still intact, cancer has not invaded the basement membrane
37
Why is it concerning if cervical cancer spreads to the ureters?
* Causes compression/blockage of the ureters * This leads to back-flow of urine * This can cause kidney failure which can be fatal
38
What is Gardasil?
HPV Vaccine
39
Important Facts about Fibroids (5)
* Oestrogen Dependent * Dysmenorrhea * Menorrhagia * Infertility * Issues during Pregnancy
40
What substances do Germ Cell Tumours produce that can help us to monitor the disease? (2)
* Beta-human chorionic gonadotrophin (B-HCG) * Alfa-feto-protein (AFP)
41
What Types of Vulval Tumours are there? (4)
* Squamous Carcinoma * Adenocarcinoma * Basal Cell Carcinoma * Malignant Melanoma
42
Why does Obesity increase risk of breast and endometrial cancers?
Body fat has an enzyme called aromatase that converts testosterone into oestrogens, and oestrogen is linked to incidence of these cancers
43
Why does Choriocarcinoma have a good prognosis (if caught on time) even though it has a high propensity for systemic metastasis to genital tract, lungs and brain?
Because the cancer cells are very rapidly dividing, it makes them incredibly susceptible to chemotherapy and radiotherapy
